en.Wedoany.com Reported - DMEGC-ESS has launched a new energy storage system designed for off-grid applications, based on lithium iron phosphate (LiFePO₄) battery technology, intended for standalone installations rather than grid-connected scenarios.

The system adopts a DC-coupled configuration, directly connecting the photovoltaic generation system to the DC side. This setup eliminates intermediate conversion steps between DC and AC, which, according to the company, helps reduce energy losses during charging and discharging processes.

The system features a modular architecture with an integrated Energy Management System (EMS), offering storage capacities ranging from 10 kWh to over 60 kWh depending on the configuration. Available in both single-phase and three-phase electrical versions, it also provides an asymmetric output capability of 150% of the rated power to handle short-term load peaks, such as motor startup, without requiring an upsizing of the entire system.

However, while DC coupling can improve efficiency by reducing conversion steps, overall system performance depends on the compatibility of the photovoltaic inverter settings used in the specific installation.

The company notes that the lithium iron phosphate chemistry is widely used in the energy storage sector. Integrating the EMS into a compact modular system is positioned as a key feature for off-grid projects requiring autonomous energy management. The system is currently being launched in the French market.
